Title: Sealing lid and sealing lid-container combination

Abstract: A lid for a plastic container, which container is particularly useful for containing paint, includes a sealing flange which engages the inner surface of a rim defining the opening of the container. The sealing flange is held in engagement with the rim by a plurality of locking tabs which are integral with the lid and fit beneath an inwardly projecting lip on the flange. The flange has a generally convex configuration while the rim has a concave configuration so that the lid is prevented from moving axially out of or into the container once it is locked in place by the tabs.
